KTAR-FM/KPKX antennas

Here's a closer view of the top of the Bonneville tower, with
the eight-bay main and four-bay backup antennas, both ERI SHPX
models. The main antenna is used by both KPKX (98.7C Phoenix,
the original station here) and KTAR-FM (92.3C Glendale), and it
is slightly beam-tilted. I don't know if the aux antenna is
also used by both stations, but it would seem reasonable.
